L mos To all wheat it may concern:

Be itknown that 1, WILLIAM L. BUReEss,

citizen of the United States, residing at Akron, Summit county, State ofDhio, have invented certain new and useful Improves meritsinVehicle-Tire Rims, ofwhichthe' follow'in'gis a specification.

Myinvention relates'to vehicle tire rims, and refers particularly to theconstruction of the locking ring whereby the latter may be readilyremoved 'fromits engagement with the rim flange of the tire rim: Y

, Heretofore considerable difliculty has been experienced in quickly andeasily removing the locking ring used in connection with vehicle tirerims. In my present invention I provide the locking ring with a cavityor recess near its end so that a tool, such as a screw driver,- or thelike, may readily be inserted into this cavity and the locking ring maythereby be removed from engagenie nt with the rim flange. In many toolabove mentioned is inserted in the ing drawings, which show a preferredem-' cavity of the locking ring the retaining flange is forced inwardlyand becomes disengaged from the inner portion of the looking ring overwhich the retaining flange extends when the various parts are in theirnormal positions. These and other advantages of my invention will bemore readily understood by reference to the accompanybodiment of myimprovements, and in of position; and Fig. l is a view si1nilar to Figs.2 and 3 except that the locking ring 1s shown as being completelyremoved from which Figure 1 is a fragmentary side elevation of a portionof a. tire rim; Fig. 2 is a transverse section taken on the line 2-2 ofFig. 1, and showing the-various parts in normal position with the toolinserted in the cavity of the locking-ring; Fig. 3 is a view similar toFig. 2, except that the retaining flange 'has been moved inwardly by thetool and the locking rin has been partly raised out Specificationof'Iettei's Patent;

this rim is. held-between the fixed flange 11 and a movable retainingflange 14', the latter being adapted to have lateral movement across theface of the rim 10.

The integral locking'ring 15 consists of an outer triangular portion 16and an in ner triangular portion 17. The upright" Wa-ll of the portion16 is'adap ted to hold the retaining flange 14 against lateral move mentwhile the inner wall of the portion- 16'engagesrovertheedge of therimflange 12: The portion. 17 of the locking ringfits within the rim'flange '12, and the,upper surface of said portion underlies the base ofthe retaining flange 14. The locking ring 15 is provided near one endwith an. aperture or recess 18 in the portion 17. In

applying the locking ring this recess 18 is placed opposite orinregister with ture13 inth'e rim flange 12.

' Having thus described the parts used in my invention, the operation ofthe same may readily be understood. Assuming thatall of the p'artsare intheir normal position, as' shown in Figs. 1 and 2, when it is desired toremove the locking ring in order to subsequently remove the tire fromthe rim, the end of a screw driver 19, or other similar tool, isinserted through the recess 13 of the rim flangd 12, the end of the toolalso passing through the aperture 18 of the the aperlocking ring. Theend ofthe tool engages ,Fig. 3, while at the same time the end of thetool 19 is gradually raised upon the v rim flange 12 as a fulcrum, sothat the locking ring i pried out of. its engagement with the rim flange12.- After one end of the lockingring has thus been .removed, the entirelocking ring may readily be pulled out of engagement with the rimflange, as will be readily understood.

It will be clear to those skilled in the art that considerable changecould be made in the detailed construction of the. parts which I havedescribed without departing from the spirit or scope of .my invention.

What I claim is: I

1. In a vehicle tire rim, the combination of a locking ring having arecess therein, and a rim'fiange adapted to receive said locking ring,-sa-id rim flange also having a recess therein which registers with therecessof said locking ring, whereby a'tool ay b'iaiaaaea-thrb gmathe.lmking.grin
